Thank you for viewing. The SIGMA USB Dock UD-01E0 is designed for CANON and allows you to update lens firmware and change settings on your PC. Everything in the pictures (the dock itself, the cap, and the USB cable) is included. It was working without any problems, but I have not performed a functionality check before listing it for sale due to the sale of the lens. As a bonus, I will include the DSLRKIT lens focus adjustment tool (used), as shown in the attached photos, so you can adjust the focus immediately after purchase. Also, since this is a used item, there may be very minor scratches from use, so please refrain from purchasing if you are looking for a product in new condition. The price is based on standard mail delivery. If you prefer anonymous shipping such as Yu-Yu Mercari, we can accommodate this for an additional 200 yen, so please contact us through the comment section before purchasing. We will revise the price after your request. Please note that we cannot change the shipping method after purchase. Thank you for your consideration.
